8. Why does wearing sunglasses protect my vision?

Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun’s ultraviolet rays. The best sunglasses are those that block out 99 to 100 percent of both UV-A and UV-B radiation. Sun exposure is associated with developing cataract and age-related macular degeneration.
